HEATING-STOVE.

To all whom it may concern."

Be it known that I, FRANK E. Bownns, a citizen of the United States, residing at Indianapolis, in the county of lVIarion and State of Indiana, have invented a new and useful Improvement in Heating-Stoves, of which the following is a specification,-reference being had to the accompanying drawings and to the letters and figures of reference marked thereon.

This invention relates to heating apparatus which is adapted to be used for heat ing atmospheric air to various degrees of temperature, and is designed more particularly to constitute the required heating apparatus of a brooder.

An object of the invention is to provide an improved heating stove for various purposes and which shall be so constructed and equipped as to be capable of efficiently regulating the heat and which shall be of simple and not costly construction.

Another object is to .provide an improved heating stove of such construction as to permit the use of various kindsof fuel, particularly wood, charcoal and various other combustible substances. A further object is to provide a heater of the above-mentioned character which shall have. simple, reliable and efiicient regulating means for controlling combustion, which heating apparatus shall be durable and economical in use.

With the above-mentioned and other objects in view, the invention consists in an improved heating stove including particularly improved draft regulating apparatus; and the invention consists also further in the novel parts and combinations and arrangements of parts as hereinafter particularly described and set forth in the accompanying claims. Referring to the drawings, Figure 1 is a front elevation of the improved heating apparatus shown as being provided with a deflector' or hood to constitute a brooder, a

' portion of the deflector being broken away;

Fig.2 is a top plan of Fig. 1, a portion of the deflector being broken away; Fig. 3 is a vertical central section of the improved heating apparatus; Fig. 4 is a fragmentary sectional elevation approximately on the Specification of Letters Patent.

line IV--IV on Fig. 2; Fig. 5 is a horizontal section approximately on the line V-V on Fig. 3; and, Fig. 6 is a fragmentary inverted plan of the top portion of the heating apparatus.

Like characters of reference on the various figures of the drawings indicate like elements or features of construction herein referred to.

As preferably constructed the improved heating apparatus comprises three supporting legs 1, 2 and 3, each leg having a supporting ledge 4 and also an upright brace portion 5, the ledges directly supporting the bottom 6 of a heater or stove, the bottom being fiat and preferably composed of sheet metal on which is a hollow cylindrical side wall 7 composed of sheet metal, the brace portions of the legs extending upward against the outside of the wall. A suitable number of standards 8, 9 and 10 are provided and vertically arranged against the inside of the wall 7 so as to be opposite to the brace portion 5 of the legs, each standard being rigidly secured to the wall by means of a rivet or securing device 11. Each standard has a foot 12 thereon that is seated upon the bottom 6 opposite to the ledge 4 of the legs and secured thereto by means of a bolt 13; and each standard has also a short arm 14 on its top, the arms supporting thereon a castiron seat-ring 15 provided on its under side with a suitable number of projecting rests 16 for a fire grate which comprises a ring 17 and cross bars 18, the ring being arranged and guided in the ring 15 and directly supported upon the rests 16. The normal forward portion of the fire grate has a downward extending projection or arm 19 rigid thereon for shaking the grate. The 1e support the bottom of the heater sufficient y high to permit circulation of air under the bottom, and the fire grate is sufiiciently removed from the bottom to prevent the fire on the grate from directly heating the bottom to an undesirable degree, the bottom being heated temperately by warm air between the bottom and the fire grate. The wall 7 is protected by means of a cylindrical fire pot 20 which rests upon the seat ring 15 and has a flange 21 on its top that is guided against the wall 7, so that an air space is provided between the wall and the fire bowl, the flange being a suitable distance from the top portion of the wall 7 to permit the upper portion of the wall to radiate the heat. The heater has a topv plate 22 which rests upon the wall 7 and has a guide rib 23 extending downward and secured to the wall. The top plate has a doorway 24 in itsforward portion and also aperturedhinge cars 25 and 25 at the rear side of the doorway, the latter being normally closed by a door or lid 26 which has curved fingers 277 and 27 that extend through the hinge ears respectively and operate therein when the forward portion of the door is swung up and backward, the

forward portion of the door having a finger hold or lifter 28. The rearward portion of the top plate has a downward extending collar 29 in which is an annular ledge 30 to support a draft pipe 31 which is inserted into the collar, this arrangement preventing moisture or gummy substance resulting from condensation in the draft pipe from flowing onto the plate 22.

' The lower portion of the wall 7 adjacent to the bottom 60f the heater has an aperture 32 therein which is below the plane of the fire grate, and the wall has also a suitable neck which is secured to the wall at the aperture to constitute an air chamber, the upper portion of the neck having an air inlet port 34 therein. The front of the neck itself is open and the side walls thereof have notched securing ears 35 and 36 thereon, the front or mouth of the neck being normally closed by means of a cap or door 37 placed against the end of the neck and being provided with lock-bars 38 and 39 adapted to be engaged with or disengaged from the ears, the cap being readily removable for the'purpose of removing ashes from the ash pit provided under the [ire grate, or for shaking the grate by means of a shaker arm 40'which preferably is rigidly secured to the projection or arm 19 and extends through the opening 32 and into a neck or air chamber.

The heater supports suitable means for automatically controlling the supply of air required for combustion of the fuel, so as to automatically regulate the heat produced as may be required. For this purpose the top portion of theneck prefcrablyis provided with'a guide yoke 41, and an arm 42 is secured to the wall of the neck and has a goose-neck shaped end portion 43 which is provided with a pivot 44 which supports a head plate 45 provided with an adjusting screw 46 to adjust the pivotal movement of the head plate which has an arm 47 thereon that extends through the yoke 41, to constitute a valve lever. An inl'et'valve struction'is protected against accidental injuryin its location within the air chamber.

it suitable thermostatic device 50 is arranged upon and suitably supported by the arm 32 beneath the adjusting screw. 46 to control the valve lever as the air surrounding the device fluctuates or varies in temperature. v v

When the heater is required to deflect or conduct radiated heat it is provided with a suitable hood 51 which'is conveniently and preferably supported by the top plate 22.

In practical use, the fuel is inserted through the doorway 24 and consumed upon the fire grate, as will be understood, the smoke or products ofcombustion escaping through the draft pipe.- As heat is developed the upper portion of the wall? becomes heated and radiates the heat to the deflector orhood which conducts or deflects the I heat. in the required direction, the shape of the hood being suitably shaped for the purpose. Heated air accumulatesunder the hood and mixing with-the atmospheric air tempers the circulating air as may be desired for the purpose. The thermostatic device operates automatically so that when a sufliciently high degreeof heat is present the valve lever is moved so as to slightly ele-' vate the valve 48 and partially close the port 34, a lowering of the temperature causing' the thermostatic device to again open the valveto increase the draft through the firegrate; the operation of the regulating devices resulting in the required'heat being automatically obtained; V 7

Having thus described the invention, what is claimed as new is-l 1.-' A heating'appliance comprising a bot tom and a sidewall, one portion of the wall having an aperture therein, a neck secured to the wall at the aperture and having an air-inlet port in the top thereof, a closure removably secured to the front end of the neck, a guide on the neck, a pivotally sup. ported valve lever guided by said guide,'a link connected to said lever and extending throughsaid port, a supported thermostatic device to operate said lever, and a valve within said neck and connected to said link to close or open said port. 7
